Title: Reactor core component vibration monitro
IPC: G01H17/00
Filed: 1973-12-21
Abstract: A method and system is disclosed which employs the neutron signals emanating from the core of a nuclear reactor to monitor reactor core component vibration, on line, during normal operation. At least two neutron detectors are disposed at diametrically opposed spaced points around the periphery of the core. The phase relationship of the spectral components of the respective signals generated by the detectors provide information as to both the magnitude and direction of the motion of the core. By subtracting the respective detector signals an out of phase signal is obtained which is proportional to the amplitude of the core component lateral vibration along the line of the detectors. Similarly, by adding the respective detector signals an in phase signal is obtained, which is proportional to the amplitude of the core component vertical vibration transverse to the line of the detectors. Additional means for normalizing the corresponding A.C. and D.C. components of the respective signals provides vibration measurements which are independent of reactor power level. The addition of a second pair of diametrically opposed neutron detectors around the periphery of the core in spaced relationship to the first pair of detectors provides information which completely defines the magnitude and direction of core vibration.

Title: Method of chemically inducing lightwood formation in pine trees
IPC: A01N43/40
Filed: 1974-09-02
Abstract: An improved method of inducing lightwood formation (resin soaking) in pine trees resulting in increased deposition of navel stores products within the trees. Lightwood induction is accomplished by treating a small area on the tree with an aqueous chemical solution which moves through the wood causing the ray parenchyma and epithelial cells to release oleoresin from the resin ducts into the tracheids and stimulating increased oleoresin production. These oleoresins are extracted from the trees by known methods and the navel stores products are recovered therefrom.
Patent ES-431652-A1 (ES)
Title: Fastener feed apparatus and method
IPC: B25C1/00
Filed: 1974-11-05
Abstract: A fastener feed assembly for a tool such as a power screwdriver having a drive member such as a rotatable bit includes a base fixed to the tool and a nose assembly slidably related to the base. The nose assembly includes a workpiece engaging surface, and when the tool is moved toward the workpiece during a fastener driving operation, the base moves toward the nose assembly. A return spring separates the base and nose assembly when the tool is withdrawn away from the workpiece. A strip of fasteners is fed from a magazine along a feed path through the nose assembly with sequential fasteners located in a drive position. Normally the drive member is spaced from a fastener in the drive position. During movement of the tool toward the workpiece in a driving operation, the drive member moves into engagement with a fastener in the drive position, and then continues to move in order to drive the fastener into the workpiece. A pawl is engageable with the strip in order to advance the strip along the feed path. During the driving operation, a feed mechanism operates in response to movement of the base toward the nose assembly to cock the pawl by moving it away from its home position along the strip away from the drive position. A lost motion arrangement delays cocking of the pawl until after secure engagement of the drive member with a fastener in the drive position. In response to withdrawal of the tool from the workpiece, the feed mechanism returns the pawl to its home position to feed an adjacent fastener of the strip to the drive position. Feed movement of the pawl is delayed until withdrawal of the drive member from the strip feed path. The strip includes a carrier with structure deformed during the drive operation for preventing reverse movement of the strip during cocking of the pawl.
